INCOME-EXPENDITURE MODEL: A macroeconomic model, which captures the essence of Keynesian economics, is based on the equality between total income generated from gross domestic product and total expenditures on gross domestic product. The cornerstone of the income-expenditure model is the consumption function, which relates household consumption expenditures to income and gives rise to the aggregate expenditure line with the addition of investment, government purchases, and net exports. The intersection between the aggregate expenditure line at the 45-degree identifies equilibrium.

ASSUMPTIONS, CLASSICAL ECONOMICS Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.
